It melts beautifully into sauteed onions and garlic before you add thawed frozen spinach and a handful of Parmesan.

Before you cook, be sure to really squeeze the spinach dry after thawing to avoid a watery casserole.

A sprinkling of buttery cracker crumbs is just the finishing touch you need for a very satisfying crunch.
